Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that a tread pattern is repeated over the outer circumference and shoulder of a tire, the opposite side perspective view being identical thereto;

FIG. 2 is an enlarged fragmentary front elevation view of the tread pattern of FIG. 1 showing our new tread pattern for the tire tread; and,

FIG. 3 is a side elevation view of the tread pattern of FIG. 1, the opposite side elevation view being identical thereto.

The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. In the drawings, the dark stippled shading is in the groove areas of the tread surface and represents the recessed portions of the tire tread, as best illustrated along the top and bottom edges of FIG. 2. 

The ornamental design for a tire tread, as shown and described.
